Despite Kevin Costner's portrayal of a rancher in the hit series Yellowstone, the show can still thrive without his involvement. This is due to the show's strong ensemble cast, compelling storytelling, and captivating setting. While Costner's character adds depth to the narrative, the show's success is not solely dependent on his presence. Yellowstone has the potential to continue captivating audiences and maintaining its popularity even if Costner were to depart from the series.
